Did you know? Sulphate-free on its own does nothing for your hair. Taking the harsh detergent out is where a good shampoo starts, not where it finishes. That is why every Watermans wash is made without sodium lauryl sulfate or sodium laureth sulfate and then puts seven actives on the scalp: caffeine to energise it, biotin for strength, rosemary to balance the scalp, niacinamide for shine, lupine protein for fuller-looking hair, argan oil for softness and allantoin to calm the scalp. Sulphate-free, vegan, made in the UK, with a 90 Day Money Back Guarantee.

How it works
Watermans gives backChemotherapy wards have had free Grow Me® from us since 2014, and the nurses there recommend it. Good karma matters to us.

Quality dedicated hair growth treatments such as the Watermans Grow Me range is an excellent starting point to consider. Diligent use for 3 to 4 months can see a reduction in hair thinning and the hope of healthier hair growth.

Month 1: scalp feels deep-cleaned and refreshed. Hair feels softer and detangles more easily.
Month 2: fewer snapped strands on your brush and pillow. Lengths feel stronger and look shinier.
Month 3: hair looks fuller and feels thicker as less of it breaks. Keep going to keep the result.
Why people trust Watermans
PETABusiness FriendDid you know?
Did you know? Sulphate-free on its own does nothing for your hair. Taking the harsh detergent out is where a good shampoo starts, not where it finishes. That is why every Watermans wash is made without sodium lauryl sulfate or sodium laureth sulfate and then puts seven actives on the scalp: caffeine to energise it, biotin for strength, rosemary to balance the scalp, niacinamide for shine, lupine protein for fuller-looking hair, argan oil for softness and allantoin to calm the scalp.
Sulphate-free shampoo is the most searched shampoo type in the UK, and most people buying one are really buying a gentler wash for a scalp or a colour that cannot take the high-street foam. Here is what the label means, how to check it, and what a sulphate-free wash can and cannot do on its own.
A sulphate-free shampoo is made without sodium lauryl sulfate (SLS) or sodium laureth sulfate (SLES), the strong foaming detergents in most high-street shampoos. It cleans with milder cleansers, foams a little less, and leaves more of the scalp's own oils and the hair's colour where they belong. Every Watermans shampoo, conditioner and mask is made this way.
You can check any bottle in ten seconds. Ingredients are listed in descending order, so if Sodium Lauryl Sulfate or Sodium Laureth Sulfate sits second or third, that is what you are washing with. Grow Me® cleans with a mild olefin sulfonate and a coconut-derived betaine instead, two cleansers that are not sulphates, and the full ingredients list is printed on every bottle and on each product page. We would rather you read it than take our word for it.
For thinning hair, a sulphate-free shampoo is the sensible base, because a scalp that is stripped four to five times a week is a scalp under strain, and a wash you are going to leave on for three to four minutes has to be gentle enough to leave on. Sulphate-free is the base. The seven actives are the point.
That is the difference between a sulphate-free shampoo and a sulphate-free hair growth shampoo. The first is a gentler wash and nothing more. Grow Me® uses the gentler wash as the carrier for caffeine, biotin, rosemary, niacinamide, lupine protein, argan oil and allantoin, and asks you to leave it on. In our independent study of 122 people, 92% said their scalp felt deep cleaned, 84% said it felt healthier and 83% said their hair looked fuller after three months.*
A sulphate-free shampoo with nothing else in it is a gentler way to get hair clean, and that is all it is. It does not energise the scalp, strengthen the strand or calm anything. Grow Me® starts sulphate-free and then does the work: seven actives in every wash, for the scalp and the strand, left on for three to four minutes.
Yes. Milder cleansers wash out less colour, which is why colourists tell clients to go sulphate-free after a tint or a bleach. Grow Me® is sulphate-free and safe on coloured hair, and Tone Me® purple shampoo is a sulphate-free toner for blonde, bleached and grey hair that needs the yellow knocked back.
Bleached hair also breaks more easily, so the strand side of the formula matters as much as the wash: biotin for strength, argan oil for softness and niacinamide for flexibility, with Condition Me® on the lengths every wash and Masque Me® once a week if the ends are rough.
Less than a sulphate shampoo, and that is the point. Foam is not cleaning; it is the detergent showing off. Grow Me® lathers enough to spread, which is all a wash needs. Wet the hair thoroughly, use two small amounts rather than one big one, and massage it into the scalp with your fingertips for three to four minutes.
If you have used sulphate shampoos for years, the first week can feel odd, because you are used to foam meaning clean. Give it the 90 days. In our study 92% said their hair felt clean after use and 89% said it felt refreshed.*
Anyone with a scalp that itches, tightens or flakes after washing, anyone with coloured, bleached, curly or Afro hair, anyone washing four to five times a week, and anyone leaving a shampoo on long enough for its actives to work. Grow Me® was tested on 104 women and 18 men with every hair type.
Watermans products are cosmetics. They care for the scalp and the hair you have, and they do not treat hereditary or medical hair loss or medical scalp conditions. If your scalp is sore, scaly or bleeding, or hair is coming out in patches, see your GP first.
122 people used unbranded Grow Me® Shampoo four times a week for three months. Here is what they said. See every result.
A gentle wash on its own is still just a wash. Grow Me® starts sulphate-free so it can be left on, then works as a team: caffeine wakes up the scalp in the first minute, and biotin, rosemary, niacinamide, lupine protein, argan oil and allantoin each do their own job over the next three. Never with sulphates, parabens or palm oil.
For the formula to work, leave it on the scalp for 3 to 4 minutes before washing out.
What the evidence says
Sulphate-free is a fact about what is not in the bottle. Here is how to check it, and what we can and cannot say it does.
On the label
Sodium lauryl sulfate and sodium laureth sulfate do not appear on the ingredients list of any Watermans shampoo, conditioner or mask. Grow Me® cleans with a mild olefin sulfonate and a coconut-derived betaine instead.
Why it matters: the ingredients list is the only claim that cannot be spun. Read ours and anyone else's.
Our own study · 2020
122 people used unbranded Grow Me® four times a week for three months. 92% said their scalp felt deep cleaned, 84% said it felt healthier, 82% said their hair felt more hydrated.*
Why it matters: a gentle wash still has to clean. This one does.
Safety
Every Watermans formula has a full independent safety assessment under UK and EU cosmetic law, with a margin of safety calculated for every ingredient, cleansers included.
Why it matters: gentle is a claim; the assessment is the evidence.
What sulphate-free does not do
Taking sulphates out makes a wash gentler. It does not make hair grow, thicken or stop falling, and a brand that implies otherwise is selling you the absence of an ingredient.
Why it matters: judge a sulphate-free shampoo by what else is in it.
What we do not claim
We do not claim that sulphate-free shampoo grows hair, treats hair loss or treats any scalp condition. We claim every Watermans wash is made without sodium lauryl sulfate and sodium laureth sulfate, that Grow Me® adds seven actives to that gentle base, and that most people in an independent study said it left their scalp feeling cleaner and healthier and their hair fuller-looking.*
Where it sits in the range
Not a sulphate-free line inside a range: the whole range. Shampoo, conditioner, mask and purple toner, all made without SLS or SLES, all made in the UK.

50 days inCustomer's own photo“After 50 days I am very pleased. My hair might not feel thicker in a ponytail but it looks thicker and you can't see my scalp through my hair any more. I have ordered my second bottle to carry on for the recommended 3 months.”
7 weeks inCustomer's own photo“I've been using this shampoo and conditioner for about 6 to 7 weeks due to my hair randomly thinning. The improvement I've seen already is amazing. My confidence with my hair is much better and I've since purchased the set again and the hair mask.”
7 months inCustomer's own photo“I've been using this shampoo and conditioner for 6 to 7 months now and the difference in my hair is amazing. The condition of my coloured blonde hair is amazing, no breakage, super soft. I love it that much I bought the salon size in both.”
Long-term userCustomer's own photo“Rapid weight loss after surgery caused dramatic hair loss. I truly thought I was going to go bald. Then I discovered Watermans and won't use any other shampoo and conditioner. My hair is in beautiful condition, it's thicker than ever and I couldn't be happier.”
First weekCustomer's own photo“I haven't been using this product for a week yet and I'm already seeing improvement. My hair is fuller, it's glossy. I also have scalp psoriasis and it hasn't bothered me at all since I've been using this product.”
2 years inCustomer's own photo“I have been using Watermans for over 2 years and the proof is in my photos. I was a tape hair extension person for years so my hair was damaged and short with ratty ends. Now everyone asks me what I use.”
Repeat buyerCustomer's own photo“I had very thin hair before this shampoo. My hair is so healthy and thick now. I don't want to use any other shampoo but Grow Me.”

Every Watermans formula is built on ingredients with their own test data, combined so they work on the scalp and the strand together.
Our actives are tested by the labs that make them. Our lupine protein was tested in the lab and on volunteers by our ingredient manufacturer. Caffeine, biotin, rosemary and niacinamide are among the most studied hair ingredients there are.
Our lupine protein is a trademarked active from our ingredient manufacturer: a hydrolysed lupine protein rich in peptides, trace elements and vitamins. It is in Grow Me® Shampoo and Grow More® Elixir.
Most shampoos lean on one hero ingredient. Grow Me® combines caffeine, biotin, rosemary, niacinamide, lupine protein, argan oil and allantoin, so the scalp and the strand are looked after in the same wash.
We have watched thousands of hair loss brands and products come and go, every one claiming to combat hair loss. Since 2012 Watermans has sold 6.5 million bottles, won a Queen's Award for Enterprise and run a three-month consumer study on 122 people. We are still standing. We must be doing something right.
Ingredient tests are carried out by the ingredient manufacturer. Our own three-month consumer study of Grow Me® covered 122 people.
FAQs
Watermans products are cosmetics. They are not medicines and do not treat medical hair loss. If your hair is falling out suddenly, in patches, or you are worried, please see your GP or a trichologist first. Prices, stock and ingredient lists on this page were checked on 12 November 2026.
Yes. Every Watermans shampoo, conditioner and mask is made without sodium lauryl sulfate or sodium laureth sulfate, and without parabens or palm oil. Grow Me® cleans with a mild olefin sulfonate and a coconut-derived betaine, and the full ingredients list is printed on every bottle and product page.
The best sulphate-free shampoo is the one that does something once the harsh detergent is gone. Grow Me® is sulphate-free and carries seven actives for the scalp and the strand, was tested on 122 people for three months, is made in the UK and comes with a 90 Day Money Back Guarantee.*
A sulphate-free wash is the right base for thinning hair because the scalp is not stripped four to five times a week, but sulphate-free on its own does nothing for hair loss. For that you want actives on the scalp, which is why Grow Me® pairs the gentle base with caffeine, rosemary, allantoin and a trialled lupine protein.
Because sulphates are the ingredient that makes the big foam, and foam is not cleaning. Milder cleansers spread and rinse with less lather. Wet the hair well, use two small amounts, and massage at the scalp. In our study 92% of users said their hair felt clean after Grow Me®.*
Yes. Milder cleansers wash out less colour, which is why colourists recommend going sulphate-free after a tint or bleach. Grow Me® is sulphate-free and safe on coloured hair, and Tone Me® is a sulphate-free purple shampoo for blonde, bleached and grey hair.
Yes. Grow Me® Shampoo and Condition Me® Conditioner are both sulphate-free and sold as a set for £26.95, with bigger bundles, a travel set and one-litre salon sizes of each. Every Watermans product except Condition Me® is vegan.
Three to four minutes on a wet scalp, four to five washes a week. The contact time is the point: a shampoo that is rinsed straight off is a detergent and a perfume. Massage it in with your fingertips, leave it, then rinse and condition the lengths.
In an independent three-month home-use study of unbranded Grow Me® Shampoo, 72% of users said their hair loss had noticeably slowed, 83% said their hair looked fuller, 82% said it felt thicker and 83% said it felt stronger. These are consumer perception results, not a clinical trial, and we say so on every page.
Grow Me® Shampoo is vegan and cruelty-free, made in the UK, and formulated without sulphates, parabens or palm oil. Every Watermans product except Condition Me® conditioner is vegan. No Watermans product is tested on animals.
Yes. The 90 Day Money Back Guarantee covers your first order of Grow Me®, Condition Me®, Grow More®, Masque Me® and Protect Me®. Use the product as directed for 90 days and, if you are not happy, we refund it. Hair grows around a centimetre a month, so 90 days is the honest minimum to judge any routine.
